What is rendering?
Converting 3D scene to 2D image.
Determine the color of the 3D scene.
Determine how object surface interact with lights.
Compute the light intensity in the scene.
What is the primary advantage of using ray tracing over rasterization?
Faster rendering times.
Enhanced realism in lighting and reflections.
Reduced computational requirements.
Simpler algorithmic structure.
When processing each scan line, the scan line algorithm:
Ignores hidden surfaces.
Only renders edges of polygons.
Determines visible surfaces and fills polygons.
Renders 3D models directly.
Which of the following effects can be realistically simulated using ray tracing?
Motion blur.
Simple shading.
Low-polygon models.
Reflections and refractions.
Ray tracing can be computationally expensive because it:
Traces multiple rays for each pixel.
Uses a large amount of memory.
Ignores light calculations.
Requires high-resolution textures.
